METAL BUILDING STRUCTURE.

Application filed August 29, 1922.

To all whom it may concern.

Be it known that I, HARRY KnAsNow, a citizen of Russia, and resident ofHartford, in the county of Hartford and State of Connecticut, haveinvented certain new and useful Improvements in Metal BuildingStructures, of which the following is a specification.

This invention relates to metallic building structures, and particularlyto columns or like elements, and the said invention relates particularlyto novel means for providing columns of the character indicated withbrackets or beam supports, although auxiliary thereto. Provision is madefor supplying the column with a cap plate having novel means bv which itis anchored and associated with beam or girder engagement elements.

It is primarily a part of this invention to provide a column of thecharacter indicated comprising a cylindrical metallic shell having acomposition filling such as concrete or the like, brackets being alsoprovided whereby beams or girders may have their ends supported instepped relation to each other on the column; and the inventioncomprises other features which results in an advantage as to thestability of the structure and the facility with which the parts can beassembled, in addition to the latitude allowed in the manner of bearingor supporting surfaces, so that proportions may be changed to suitparticular requirements without necessitating change in the fundamentalstructure of the device.

It is a further obiect of this invention to provide a bracket, the baseof which is shaped to the curved contour of the outer wall of the saidcasing.

With the foregoing and other objects in View, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this application wherein likecharacters denote corresponding parts in the several views, and inwhich- Figure 1 illustrates a view in elevation of the upper end of acolumn showing the same equipped with column supporting devicesembodying the invention;

Serial No. 585,028.

Figure 2 illustrates a sectional View on the line 2-2 of Fig. 1;

Figure 3 illustrates a vertical sectional view thereof;

Figure 4: illustrates a perspective view of the cap plate inverted;

Figure 5 illustrates a perspective view of the column with the cap plateremoved;

Figure 6 illustrates a view in elevation of the upper end of a columnshowing a girder in section;

Figure 7 illustrates a view in elevation showing fragments of twosections of a column with fastenings for anchoring one on the other; and

ld'igure 8 illustrates a view in elevation showing the application ofthe invention to a fragment of a building.

In these drawings 10 denotes the shell of the column, 11 the concretecomposition filling for the same. In the present embodi' ment of theinvention, the column supports comprise T-shaped brackets, the bases 12of which are curved to the contour of the shell and are intended to fitclosely thereagainst when they are secured in place by fastenings 13such as rivets or the like. The inventor does not wish to belimited withrespect to the fastenings, and under certain conditions, bolts could beemployed and, of course, the shape of the head of the rivet isimmaterial. The web 14 of each bracket may extend outwardly from thebase to any appropriate degree, depending upon the area desired for thesupport of the beam. Preferably at the upper end of each web, angleplates 15 are secured to the sides of each web, and the flange of theangle plate which is not secured to the web has its outer face inalinement with the upper edge of the web, and by this construction, arelatively wide base or support for the I-beam or girder will beprovided. Of course it will'be understood that the area or sizes of thesupporting flanges of the angle plates may be increased or diminished tosuit particular requirements. It will also be understood that the numberof brackets may be increased or diminished, according to the number ofbeams to be supported, and their positions with relation to theperiphery of the column may be made to accord with the direction Whichthe beam is to extend from the column.

In order to increase the sheer resisting effeet in the construction, areinforcing plate 16 may be applied to the interior of the shell whereeach of the brackets is to be attached. When these plates are added, thelastenings or rivets will, of course, project through them and they willbe secured in place simultaneously with the fastening of the flanges ofthe brackets.

The cap plate 17 may be secured in place in two ways, as illustrated.@ne of the means consists in providing the cap plate with apertures 18to receive fastening-s 19 that extend therethrough and through theflanges of the angle irons; and the other method contemplates the use orflanged elements 20 that are secured to the under side of the cap plate,the said flanged elements having lips 21 that engage cleats applied tothe interior of the shell, in the present embodiment of the invention,in contact with the reinforcing plates, and they may be secured by thesame fastenings which are employed for ias'i'ei'iing the reinforcingplates. In some constructions, the reinforcing plates will be omittedperhaps, and in that event, cleats will be secured against the innersurface of the col um For most purposes, two cleats and two engagingelements carried by the cap plate will be employed, and when the capplate is secured to the column, the cleat ei'igaging elements will beout of alinement with the cleats, and then by turning the cap plate,there will be an interlocking engagement between the cleats and theengaging elements, and when the shell is filled with concrete, partswill beheld in proper positions.

in some structures, the cap plate will be omitted, and in that event,the Fangcs of l-beams may be secured directly to the flanges of theangle irons by appropriate lastenings such as rivets, and inventor doesnot wish to be limite with respect to this application of the invention.

In Figure 8 a column shown, associated with and supporting a relativelyheavy llbe'am 22 associated with a bracket 23 7 adapted to support arelatively lighter lbeam 2% wherein the supporting surfaces of the twobeams are on the same plane. ln this construction, the bracket has a weband flange that is longer than the web of the bracket which supports thel-beam 22. The illustration just described is turnished for the purposeof illustrating the various ways by which the same invention may be usedin practice, and, of course, other modilications as to proportions willpresent themselves to those skilled in the art. The bracket 23 may havea web longer or shorter in order that it will support beams of otherdimensions in the same relation to the beam 22 as that shown, and thenumber of brackets en'iployed may also be varied to suit particularrequirements.

ln Figure 7, a joint between two sections 2;? and 26 of column isillustrated, in which the brackets are oi the same construction as thoseheretofore described, but in this constri'iction, the flanges of theangle irons oil one bracket are secured to the flanges of the angleirons oi' the superimposed section, and by this means, continuous columnis forn'ied. Furthermore, in this illustration, only two brackets of onesection are shown as secured to two brackets of the other section, andan l-beam 2'i'isillustrated as being supported on the bracket of thelower section, and this illustration is provided convey the idea thatthe brac lets a means for coupling may be used either as as a supportfor a sections together, or beam.

It is also observed that the brackets on the lower section constitutewhat may be termed caps, and the brackets on the lower end of the uppersection may be regarded as bases, so that when the caps and bases aresecured together, the structure braced against lateral strain to a verymarked degr e, the advantages of which will be apparent.

In the construction shown in Fig. 6, the brackets 28 constitute caps onwhich girder seats 29 may be secured in appropriate manner to retaingirders 30 against displace- .ieut. The girder seats may be formedeither of channel iron or angle irons, as those skilled in the art willunderstand.

The brackets are formed ol steelc and c bases thereoi are forged havinga curve of the proper arc so that it will conform to tie outer suriaceof the column to which the bases are to he applied.

1' claim:

1. In a metal structure, a cylindrical shell, brackets comprising steelbases shaped to the contour oi the outer surface or the shell and havingwebs projecting therefrom, angle irons secured to the webs their outeredges and constituting supports, reinforcing plates on the inside of theshell, and fastenings cal ending through the bases of the brackets, theshell and the said reinforcing plates.

In a metal structure, a cylindrical. shell, brackets comprising steelbases shaped to the contour of the outer surface of the shell and havingwebs projecting therefrom. angle irons secured to the webs at theirouter edges and constituting supports, means for securingthe said basesto the shell, cap plates for the column, cleats on the inside or thecolumn. meml'iers carried by the cap plate adapted to interlock with thecleats, and a composition within the shell for holding the cap latefasteniugs in place.
